I have noticed that I am getting better results with an original
method of Chomczynski & Sacchi (Anal Bioch - you can find reference
from Medline probably - if not, write me). In my hands TRIZOL was a
big disappointment. It was giving quite a messy total RNA preparation.
The original method is not really more comlicated than TRIZOL. It only
looks so. Of course, you have to make reagents yourself (nothing
really difficult)
